Llama IgG2b Fc Protein, Tag Free (MALS verified) | IGB-L5204-1mg| Gentaur Distribution US, UK & Europe
Immunoglobulin G2 (IgG2) is a member of many immunoglobulin G developed and secreted by effective B cells. In wake of cutting by pepsin, IgG is divided into two F (ab) s with one antigen binding site and a high conserved Fc segment. The Fc segment bears a highly conserved N-glycosylation site. There are two members of IgG2: IgG2a and IgG2b. It was found that IgG2a was superior to IgG1 in activating complement. The glycosylation of the circulating immunoglobulin-γ (IgG) antibody molecules changes in rheumatoid arthritis. Ig gamma-2 chain Fc region contains two constant regions of IgG2 H chain (CH2, CH3).
Source: Llama IgG2b Fc, Tag Free (IGB-L5204) is expressed from human 293 cells (HEK293). It contains AA Glu 1-Ser 243 (Accession # AAX73259.1).
